Neurodiagnostic Week - Third Week in April
(Last Updated On: November 9, 2022)


The third week in April is Neurodiagnostic Week. The purpose of the week is to acknowledge the year-round efforts of the Neurodiagnostic professionals around the world. It is an opportunity to educate others, recruit new students into the profession, and to promote neurodiagnostic awareness in the community. It is also a great time to celebrate the individual accomplishments of neurodiagnostic technologists everywhere.

Neurodiagnostic Technologists work in the fields of:

  • Electroencephalography (EEG)
  • Evoked Potentials (EP)
  • Intraoperative Monitoring (IONM)
  • Long Term Monitoring/Epilepsy (LTM)
  • Continuous EEG in the Intensive Care Units (cEEG/ICU)
  • Nerve Conduction Studies (NCS)
  • Polysomnography/Sleep Studies (PSG)

HOW TO OBSERVE #NeurodiagnosticWeek

  • Follow on social media #NDWeek.
  • Invite an EEG tech to speak to your group, your school, your brown-bag lunch.
  • Watch a video about becoming a Neurodiagnostics tech.


1929: Mapping brain activity started in German with the first the electroencephalogram (EEG).
In the 1950s, EEGs were performed in major medical centers and filtered into private practices.

1959, ASET – The Neurodiagnostic Society is organized. It is the largest national professional association for individuals involved in the study and recording of electrical activity in the brain and nervous system. ASET’s mission is to provide leadership, advocacy and professional excellence for our members, creating greater awareness of the profession and establishing standards and best practices to ensure quality patient care.

1984: ASET, the American Society of Electroencephalographic Technologists sponsors the first National EEG Awareness Week.

1986: Digital instruments for all-night sleep recordings and long-term monitoring appear.

Neurodiagnostic Techs record and study the electrical activity of the brain and nervous system in a variety of ways. They work with patients who have diagnoses of epilepsy, coma, sleep disorders, tumors, strokes, and countless more diseases, injuries, and conditions of the central and peripheral nervous systems.
